The tool imports meshes and textures, but not scene objects, such as cameras, fog or shadow casters.

In addition, animated content – one of the headline features in Toolbag 3 – is not supported, with animated meshes being imported in the base pose.

The importer supports most “common material modules”, though not some of UE4’s advanced modules, including secondary reflections, anisotropic reflections and detail normal maps.

Assets created using specular maps are automatically converted to use Unreal Engine’s metalness shaders, although for best results, Marmoset advises users to use a metalness workflow – or simply Toolbag’s own Unreal Engine 4 preset material – from the outset.
